Abstract We have performed EELS analysis of poly (ethylene terephthalate) (PET) in the analytical TEM in order to evaluate the possibility to obtain chemical analysis of the polymer at sub‐micrometer scale. Due to irradiation damage, it revealed necessary to work at the lowest possible electron dose, typically below 10 3 C.m −2 , and with the specimen cooled to liquid nitrogen temperature. In the acquired spectra, we propose an identification of the different chemical bondings in agreement with XANES experiments.
